Stratos ECO Circulators

wilo small wet rotor circulators ecm smart automatically controlled circulators
WILO Small Wet Rotor CirculatorsECM “Smart” Automatically Controlled Circulators
  • Stratos ECO Cast Iron & Bronze
  • ECM (Electronically Communicated) technology
  • Smart pump adjusts flow to system changes
  • Auto setback
  • Anti-seizing feature
  • Easy wiring quick connectors
  • Easy set-up (∆p-v in feet of head via red button)
  • Interchangeable with all competitors
  • Replaces 12 competitor’s types
  • 115 and 230 volt, models, cast iron & bronze
  • Max temp 230 deg F, min temp 60 deg F
  • Maximum pressure 145 PSI
  • Minimum pressure – see sheet
  • Maximum wattage 59, minimum wattage 5.8
  • Class “A” energy rating

Eco 16 FX & BFX Model

Eco 16 F Model

slide3

Model Number Designation

ECO 16 ( ) FX

  • 16 = Maximum Head in Feet (adjustable from 4’)
  • B = Pump Housing (Volute) Material
    • (B for Bronze, no Letter for Cast Iron)
  • FX = Pipe Connection
    • F = Flanged
    • FX = Flanged Rotated
slide4

Benefits - External

Fits all Competitors’ Models

(2 Bolt Residential Flanges)

2 Allan Screw Connection

Automatic Air Venting

(Inspection and Service Screw)

Red Button Sets Head (∆pv in feet)

Also Activates/deactivates Setback

Sizing Examples

  • Sizing Examples – Simplified Heating
  • Determine BTU’s and Temperature Differential (mostly given)
  • Calc Flow (USGPM) = BTU per hr/500 (constant)/temperature diff deg F
    • EG: 10 USGPM will pump 100,000 BTU/hour @ 20 deg F differential
  • Once flow known size pipe based on max velocity of 4 ft/sec
    • Higher velocities cause noise, erosion and air problems
  • Once pipe sized estimate friction loss
    • Manifold systems heads are not additive – use the highest loss loop
  • Once friction loss and flow are determined match point to curve
  • Remember to use the correct companion flanges
  • Rotate Inventory!
slide7

Installation Instructions

  • Install with shaft horizontal
  • Pump in any direction (vertical, horizontal etc.)
  • If pumping vertical try to pump up (with air)
  • Locate in system where suction pressure as high as possible
  • Pump away from the thermal expansion tank!
  • Fluid should be relatively free of abrasive particles
    • Damages sleeve bearings in wet runners and mechanical seals in dry runners
    • Do not use any stop leak products (see label)
  • Install with terminal box @ 9:00, 12:00 or 3:00 positions
    • Installing @ 6:00 can allow fluid into terminal box during air bleeding
  • Do not install at the highest point (air)
  • Do not install at the lowest point (dirt)
  • Be careful with the suction side (laminar flow)
slide8

Application Examples

  • Applications
  • Cast Iron (Ferrous) Models
  • Primary and Secondary Hot and Chilled Water Systems
  • Up to 50 % Maximum Glycol – DO NOT USE STOP LEAK PRODUCTS!
    • Closed loop (airless) hot and cold circulation systems (60 to 230 deg F)
  • Bronze (non-Ferrous) Models
    • Open loop systems (ie Domestic HW Recirculation) – Max Temp 150 deg F (66 deg C)
    • Higher temps can cause precipitation of Calcium in hard water applications
  • Maximum working pressure 145 PSI
  • Minimum inlet pressure
    • 0.7 PSI @ 122 deg F (50 deg C)
    • 4.4 PSI @ 203 deg F (95 deg C)
    • 14.5 PSI @ 230 deg F (110 deg C)
  • For indoor use only
